Abstract (en)
[origin: EP2827131A1] An image inspection apparatus according to the present invention uses inspection region defining information including information defining an initial contour of an inspection region and information defining a range based on the initial contour as a search range for searching a contour of the inspection region. The contour of the inspection region is generated by setting a plurality of base points on the initial contour and performing edge search processing on a line that passes through each base point and intersects with the initial contour, within an area of the search range of the inspection target object image, to determine an edge point corresponding to each base point, and by connecting or approximating a plurality of the edge points thus obtained.
